A small block is given a velocity `v` from point `A`. Given `x = 3R,R = 20 m` and `g = 9.8 m//s^(2)`. If the block strikes the point `A` after it leaves the smooth circular track in vertical plane, the value of `v` is `7x`, find `v` ?
.

In the block moves up with constant velocity v m/s. Find F

A particle is given a horizontal velocity u, from the point P on a smooth horizontal floor which has a vertical circular track at the end. ABC is a semicircular track of radius r in the vertical plane. If the path length PA is x = 3r and the particle returns to point P, then the initial speed of the particle is

If orbit velocity of planet is given by v = G^(a)M^(b)R^(c) , then

A cubical block of side a is moving with velocity v on a horizontal smooth plane as shown. It hits a ridge at point O. The angular speed of the block after it hits O is:
